Open Source BSD Semantic Web Software

This project is no longer actively maintained. It is succeeded by the Eclipse RDF4J project, which can be found at GitHub and at http://www.rdf4j.org/. Sesame is a de-facto standard framework for processing RDF data. This includes parsing, scalable storage, reasoning and full SPARQL 1.1 query/update support. Sesame offers a fully modular toolkit and an easy-to-use Java API that can be connected to all leading RDF storage solutions.

Semantic MediaWiki is an extension to the MediaWiki software (powering Wikipedia), which extends the Wiki with ideas from the Semantic Web. We focus on usability and tight integration. See the web site for further details and GitHub at https://github.com/SemanticMediaWiki/SemanticMediaWiki/releases for the file releases! (since version 2.4.0).

PHP class to parse several feeds at same time and give ordered result. Support RSS 0.9x/1.0/2.0, RDF, and Atom. Support some namespaced modules like Media RSS, iTunes, Dublin Core, and more... Include class to make RSS rewriting or filtering.

The London Datastore (http://data.london.gov.uk) was created by the Greater London Authority (GLA) as an innovation towards freeing London’s data. This SourceForge Project will be used to Open Source our development efforts surrounding data formats

MapPSO is a tool for Ontology Alignment, which uses Discrete Particle Swarm Optimisation. A particle swarm is used to search for the optimal alignment. The algorithm is massively parallel and adapts naturally on parallel architectures.

A library to allow query a SPARQL end-point in Python

dotNetRDF is a .Net Class Library for working with RDF and SPARQL programatically built with C# 3 for the .Net Framework 3.5/4.0/Silverlight 4 and WIndows Phone 7. It provides a simple object model for representing RDF, SPARQL Queries and Updates and understands all common RDF and SPARQL syntaxes. Extensive documentation is available on the website and support is available via the mailing lists.

A project designed to create a standard mapping of RDF to Java.

Our aim is to enable Web applications to consume linked data from the Web. With SQUIN (Semantic Web Query Interface) we will provide a Web data query service as an addition to the LAMP technology stack. This service executes queries over the whole We

Smart-M3 is a functional platform that provides a cross domain search extent for triple based information. Smart-M3 enables smart cross domain applications that rely on information level interoperability.

Arastreju is a Java based engine for ontology based information management.

Network software for annotation and quality control of distributed data. Supported by NSF: DBI 0646266 and NSF: DBI 0960535. http://wiki.filteredpush.org

*** PROJECT NOT MAINTAINED ANYMORE *** RDFStats generates statistics for RDF datasets behind SPARQL-endpoints and within single RDF documents.

This project is a reasoner for the description logic EL+. It computes the concept subsumption hierarchy. It is an OWL 2 EL reasoner.

Metadata.net is a collection of website components and tools for creating and using metadata produced by the eResearch Group at ITEE, University of Queensland.

OntoComP is a Protégé 4 plug-in for completing OWL ontologies. It enables the user to check whether an OWL ontology contains "all relevant information" about the application domain, and extends the ontology appropriately if this is not the case. It achieves this by asking the user questions of the form "are instances of classes C1 and C2 also instances of class C3?". If the user confirms such a question, then a new axiom of the application domain that does not follow from the ontology has been discovered, and it is added to the ontology. If the user rejects it, the user has to give a counterexample to this question, i.e., an individual that is an instance of C1, C2 and not C3. When all such questions (about some initially given classes) have been answered, the ontology is complete with respect to the application domain.

AnnoCultor: porting cultural repositories to the Semantic Web.

The Common Lisp Reasoner extends the Common Lisp Object System (CLOS) to incorporate a powerful rule language suitable for all kinds of reasoning tasks, vanilla XML and RDF/XML interfaces, and support for a variety of AI-related applications, such as scheduling, planning and diagnosis.

DB2RDF is a a software tool that will convert data from relational data model to semantic data model (in the form of RDF and RDFS). A SPARQL endpoint for querying the converted data. For querying the semantic data, SPARQL query language is used.

DODDLE-OWL is a domain ontology development tool for the Semantic Web. DODDLE-OWL makes reuse of existing ontologies and supports the semi-automatic construction of taxonomic and other relationships in domain ontologies from documents.

A set of tools (command line and GUI) to provide a complete digital photo workflow for Unixes. EXIF headers are used as the central information repository, so users may change their software at any time without loosing any data.

Microsoft .NET connector for the Fedora Commons repository system. Developed by Jeroen Suijkerbuijk, commissioned and sponsored by Maastricht University Library.

Glue 2 is a Semantic Web Service discovery engine fully compatible with the WSMO meta-model and the WSML language that aims at solving polarization problems by using mediators.

HERAKLES is a reasoning broker framework for OWL (Web Ontology Language) reasoning systems.

A Java library which reads an OWL resource, e.g. an OWL file, and offers methods to get the contained information. For that is has methods to get all OWL classes together with their subclasses and their data types (i.e. their data properties), all relations of these OWL classes (i.e. all object properties), all OWL individuals together with their classes and their data values (i.e. their positive data property assertions) and all relations of these OWL individuals (i.e. all their positive object property assertions).
